Study Notes
Hyperlipidaemia and Dyslipidaemia: Key Facts and Considerations
- Lipids are necessary for normal body functioning, but abnormal levels of cholesterol and triglyceride are modifiable risk factors for cardiovascular disease (CVD).
- Hyperlipidaemia and dyslipidaemia are terms used interchangeably to describe abnormal blood lipid profiles.
- Dyslipidaemia can be caused by genetic defects, metabolic dysfunction, and certain diseases.
- Diet, body weight management, physical activity, and exercise are important interventions for blood lipid control.
- Lipids serve various physiological roles, including energy storage, hormone production, and cell membrane structure.
- Dyslipidaemia is strongly associated with an increased risk of CVD, as arterial atherosclerotic lesions develop and progress with age.
- The relationship between triglyceride concentrations and CVD incidence is still debated, and various factors can influence the association between blood lipids and CVD outcomes.
- Despite the need for cholesterol medication, many adults in the US are not taking it, especially those at high risk for CAD.
- Lipoprotein metabolic pathways involve key enzymes and transfer proteins that facilitate the transport and metabolism of lipids.
- The LDL receptor pathway delivers cholesterol to extrahepatic tissue, while reverse cholesterol transport returns lipids from peripheral tissue to the liver.
- Postprandial lipaemia, the elevation of blood triglyceride levels after a meal, is associated with increased CAD risk and can be influenced by genetic factors, exercise, and nutrient composition.
- Metabolic dyslipidaemia, specifically triglyceridaemic dyslipidaemia, affects the vascular endothelium and can lead to diminished vascular function and increased inflammation.
Hyperlipidaemia and Dyslipidaemia: Key Points
- Hyperlipidaemia and dyslipidaemia refer to abnormal blood lipid profiles, with dyslipidaemia being a combination of genetic, environmental, and pathological factors.
- Most severe forms of dyslipidaemia and dyslipoproteinaemia are linked to genetic defects, while secondary dyslipidaemia is usually a result of metabolic dysfunction.
- Diet, body weight management, physical activity, and exercise programming are important interventions for blood lipid and lipoprotein control.
- Lipids serve crucial physiological roles in the body, including energy storage, hormone production, and maintenance of cell membranes.
- Dyslipidaemias are associated with a greater risk of cardiovascular disease (CVD), with the development of arterial atherosclerotic lesions being significantly related to cholesterol and triglyceride levels.
- The association between triglyceride concentrations and the incidence of CVD is still debated, and various factors can influence the strength of this association.
- Many individuals needing cholesterol medication are not taking it, and statins are the most commonly prescribed lipid-lowering agents.
- Atherosclerotic disease processes start in childhood and involve the transportation of lipids through lipoproteins and the action of enzymes and transfer proteins.
- The LDL receptor pathway and reverse cholesterol transport are two important pathways involved in the metabolism and movement of lipids.
- LDL particles deliver cholesterol to tissues via LDL receptors, while reverse cholesterol transport involves returning lipids from peripheral tissue to the liver for metabolism and excretion.
- Prolonged postprandial lipaemia, or elevated blood triglyceride levels after a meal, is associated with increased CAD risk and harmful events such as endothelial dysfunction and arterial plaque buildup.
- Metabolic dyslipidaemia, specifically triglyceridaemic dyslipidaemia, affects the vascular endothelium and can lead to reduced nitric oxide production, inflammation, and diminished vascular compliance and reactivity.
